Application filed December 15; 1922. Serial No. 607,231.

To all whomit may concern B tkno a IJ-lminr J Shrewa i iz of he U it d S a es, and esident of; New York; city,New York, have invented certain. new. and useful Improvements; in LOOSE-Leaf Binders, of which the following s a; spe ifie i ns- This, invention relates to binders of llll: proved type alldis provided with adjust-able means whereby sheets having differently spaced perforations may be properly en.- g dby' thep ts of the. binde Heretofore. loose lea't'binders have usually been provided with fixed, posts adapted to engage perforations of fixed spacing; in the loose leaves. Difl'erent manufacturers of binders have adopted different spacing-stoitheposts and they usually] supply'loose leaves. tofit their own particular "binder. This necessitated the user purchasing the particular leaves supplied by the binder manufacturer. This lack of standand'ization of spacing of theyperforations in the leaves has oftencaused considerable inconvenience to users of loose leal' binders as the leaves perforated in one way wereoften ruled or otherwise marked in a; desirable, way but could not be used by owners of; certain binders because the Poets of their binders were spaced differently than the perforaiozis nis ehr e v s invention aims to overcome these oh jeetions and provides means.- whereby the pe t areeapable of most uni aladjus mentand hence my binder; can be used with leavessupplied by various manufacturers;

Oth r. iects nd, advantages t y invention .will be apparentfrom the following specification when read in connectio'u with theaecompanying drawiilgs; and the novel features will, be defined in the appended l ims.

Fig. 10 is a sectional detail of a modifi cation.

Referring first to Fig. 1 my improved binder comprises an upper niember 10, a lower member 12 and covers 1st and 16 hingedly secured to said upper and lower members. The upper member 10 is provided' with a plurality 01' cars or lugs 18, and the cover 14 is provided with a hinge portion 20 and a rod22 passes through the ears and said hinge portions forming a pintle about which the cover. 14 may be rocked. The lower member 12 is provided with lugs 24 and the cover 16-is provided with suitable hinge portion 26 and a. similar rod 28 forms a pintle about which the cover 16 can be rocked.

The lower member 12 is preferably made in the form of a sheet-metalcasing having a lower wall 30 and upperrflanges 32wliich partially enclose blocks 3% and 35. These blocks are loosely mounted in the casingand are adapted to be moved or propelledjtherein by means of" screws 36 and 38 which are in threaded engagement. therewith. The inner ends of the screws 36 and 38 are provided with journal portions l0 and 42 adapted to rotate freely in a bearing block 4% secured to the member. 12 by a bolt or other fastening device 45. On opposite sides of the blockde the screws 36 and 38 are each provided with suitable collars gtfito prevent endwise movement of the screws. The outer endsof thescrewsare provided with squared ends d8 for co-action with alzey by which they may be rotated in order to propel the blocks 34 and 35. The block oecarries a post 52 and the block 36' carries a similar post 54. At the end-of each of these posts is a screw-threaded shank 56 which engages a suitably th readedlsocket in the corresponding supporting block. The upper end oft each post is .provided with a threaded cavity 58 andthiscavity is adapted to receive the threaded end 500i a similar post, it the binder is to support a great thickness of leaves or if, as illustrated, a comparatively small number of leaves are to be held in place a cap having a shank 62 is secured to the top of the post.

From the above it will be clear that by turning either of the screws 36 or 38 by means for example of a suitable key as illustrated at 50 in Fig. 9, the posts can be adjusted so as to bring them into position to register with the perforations in a selected type of leaf. The inward movement of the post-carrying blocks 34 and 35 is limited by the fixed block 44 and the out- L ward movement of said movable blocks is limited by caps 64 and 66 secured in the ends of the member 12.

I have provided improved means where by the loose leaves can be held in clamped position between the opposed members 10 and 12 and my improved clamp is arranged to engage a corresponding post carried by the lower member in any one of its various adjusted positions. The structural details of this clamp are best shown in Figs. 4 to 8. As shown in Fig. 4 there are two such clamps, one indicated at 74 for engagement with the post 52 and the other indicated at 76 for engagement with the post 54. The clamps are of identical construction and hence a detailed description of one will suffice for both. Each clamp comprises a plate 78 which is pivoted at 80 to its corresponding supporting block 82 or 84. Each plate 82 operates within a slot 86 formed in the block and this slot is covered by a plate 88 which has an aperture 90 formed therein to permit free movement therethrough of a stud 92 which is riveted or otherwise se cured to the plate 78. This stud 92 carries on its upper end a knob 94 and the portion of the stud between theplate 88 and the pivoted plate 78 is surrounded by a spring 96. This spring tends to normally hold the pivoted plate 78 in frictional engagement with the post carried by the member 12 of the binder. Reference to Fig. 5 will clearly show that the pivoted plate '1' 8 forms an effective clamp which is adapted to grip the post at any pointin its length so as to hold the member 10 in any desired spaced relationship with respect to the member 12 according to the thickness of the pack of leaves to be secured in the binder. To release the clamp it is merely necessary for the user to grasp the knob 94 and elevate it slightly so asto free the post from the grip of the pivoted clamp plate.

Each clamp is carried by a corresponding block 82 or 84, as above stated, and these blocks can be adjusted by means of lead screws 98 and 100 so as to bring the clamps into proper position for co-action with the posts carr'ed by the blocks 34 and 35. The blocks 82 and 84 are guided within the walls of the member 10 and the screws,

for operating them are secured for rotar movement in a central block 102 in muci the same manner as the screws 36. and 38.

previously referred to.

From the above it is thought that it will be clear that in order to position the posts for engagement with the perforations in the loose leaves to be used, it is merely necessary to turn the feed screws 36 and 38 so as to bring the posts 52 and 54 into register with the perforations in the leaves. After this has been accomplished the screws 98 and 100 are operated so as to bring the turn the screws by means of a suitable key as illustrated in Fig. 9 so as to move the posts from the full line position, fotexam ple, to the dotted line position in order to adjust the binder for use with sheets perforated to correspond with the dotted lines as indicated in this figure.

If desired, I may provide in the upper clamping member 10 a single lead screw as illustrated at 68 having right-handthreads as at 70' on one end and left-hand threads as at 72 on the other end as shown in Fig. 10, so that by turning the single lead screw both blocks 82 and 84 can be simultaneously moved in either an inward or an outward direction. The same arrangement may be used for the blocks 34, 35 for the posts.

Though I have described with great particularity the details of constructionof the particular embodiment of the invention herein shown, it is not to be construed that I am limited thereto as changes in arrange ment and substitution of various expedients may be resorted to without departing from the spirit and scope of the invention as defined in the appended claims.

What I claim is:

1. A loose leaf binder including a pair of opposed members between which the leaves are adapted to be held, posts mountedffor adjustable movement in one of sa-id members, clamps carried by the other member, and means for moving said clamps to position them for proper co-action with the posts in any selected position of saidposts.

2. A loose leaf binder having posts adapted to engage perforations in leaves, means for adjusting the position of said postsfor too,

engagement withsheets having perforations of a selected spacing, clamping means arranged to co-act with said posts and means for moving said clamping means to position for co-action with said posts.
